Figure 4: CD14⁺ VNN2^high cells do not express markers for T cells, NK-cells and B-cells.

A) One hundred percent of magnetically bead-enriched CD14⁺ cells expressed CD33 and CD11b, although they were negative for CD15. B) The subset of CD14⁺ VNN2^high cells did not express any CD19 or CD3, but did express very low levels of CD56 (13%). C) Expression of CD19, CD56 and CD3 on CD14⁺ HLA-DR^neg/low Mo-MDSC was negative for all markers examined. Open peaks represents positive staining, grey filled-in peaks shows represent isotype controls. In some figures both peaks are almost superimposed due to nature of staining.
